ls: unrecognized/unknown option «--color [»

[Moltke]

Often there are predefined aliases. For Example in my system there are for example those aliases:

alias cd..='cd ..'
alias c~='cd ~'
alias la='ls -a | grep '\''^\.'\'' | column'
alias ls='ls --color'

By predefined you mean predefine "by user" or "by the system"? I could use ls command before without any issues whatsoever and I haven't created any aliases for it.

don't know ... mine working well ... whats the directory you are trying to get ls from ... maybe you are asking without giving root permission

Mine was working fine too last time I checked. No need for root when using ls command.
